Mobility meta means that everybody who actually has a brain with just side step the Q and laugh at you while you just wasted time to try and knock them up. I'd rather scream minions at people and pretend Sion is at all relevant.

I'm trying to use it to actually do something more than activate my W and bumrushing into a teamfight with R. Which is exactly the problem that old Sion had, relying on TWO abilities.
Narasimha8 votesYou use it to zone. Especially in lane, because in teamfights, you're going to hit SOMETHING. But in lane, you always want to make sure that your Q is going to throw off your enemy. Aim it so that it hits some of their minions. Time it so that they can't go for your cannon minion about to die. Make them fear it because, like a Blitz Q, one good hit is all you need.

GhostOfShrimpmas5 votesSo, why not aim your Q at your own ADC, so that people will stay away from it? You don't need to use it as an easy to dodge stun, you can use it as an area denial tool. The big red target indicator is essentially a wall that your foes can't cross.
Baron of Bread1 votesThe best part is when they try to cross and then your ADC gets to kill them.

ThePlasticSpork2 votesYou can't seriously be implying that Sion isn't relevant right now
Use your Q for area denial. If you're just walking up to people and trying to Q them you deserve to fail.

Nah that would mean giving him a chance against 
RogueWill1 votesIf you land a slow first then is quite easy to hit your Q, unless you are jungle you are not supposed to start Q with any combo, it is supposed to be a folow up ability
UPfreely1 votesi dont think they did it to try to get you to max Q, they did it as compensation for the nerf to e
flibitydoo1 votesIt's hilarious during a teamfight when the enemy kha'zix thinks that they can just walk past Sion.
Not only does my E slow you so it takes even longer to walk into leap range, but it also shreds your armour so my ADC kills you even faster.

Kuroi861 votesBest way to hit Q I've found it to first hit the E and then charge Q just enough to hit them. Don't bother with max charge. Another great thing is initiating with ult up lane to follow up with charged Q for knock up.
ProfDrDeath1 votesAlso, in some lanes, it can still be helpful to max Q over E. For example, I played a Morgana some days ago - and it ended up in an AFK pushfest after our jungle got me first blood at level 3. So, I maxed Q to be able to counterpush.
Anecdotes aside, Q is a superb area denial tool. As was already said here, place it below your ADC in a teamfight and dare them to dive him.
